Description

Technical Field

[0001] This utility model relates to the field of resin grinding wheel technology, specifically to an anti-locking dead angle grinding disc. Background Technology

[0002] Angle grinders, as high-speed rotating grinding tools, are widely used in metal processing, construction and decoration, and other fields. During operation, the grinding disc may suddenly jam or overload, causing the output end to seize up and generate a huge recoil torque. This impact force is instantly transmitted to the angle grinder body and the operator's arm, which can easily cause equipment damage, grinding disc breakage and flying debris, and other safety accidents, causing serious injury to the operator.

[0003] Existing angle grinding discs mostly employ rigid connection structures, lacking effective buffering and energy absorption mechanisms, and thus unable to absorb and disperse impact energy in a timely manner under seizure conditions. Furthermore, traditional resin grinding wheels are prone to internal cracking due to centrifugal force and thermal stress during high-speed rotation, leading to shortened wheel life and potential breakage risks. Therefore, there is an urgent need in the field for an angle grinding disc structure that can effectively prevent seizure impacts and improve safety and durability. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution: an anti-locking grinding disc, comprising a central flange and a resin grinding wheel, specifically: The central flange is provided in two sets, including a first flange and a second flange. A stress-relieving device is provided between the first flange and the second flange. The stress-relieving device can be used to collapse and relieve stress after the output end of the angle grinder is locked. The resin grinding wheel is provided on the outer ring of the first flange. An elastic buffer layer is provided between the resin grinding wheel and the first flange. A crack-inhibiting mesh is embedded inside the resin grinding wheel.

[0005] Preferably, the first flange and the second flange are arranged in parallel, and the diameter of the first flange is larger than the diameter of the second flange.

[0006] Preferably, the outer ring of the connecting holes of the first flange and the second flange is provided with a plurality of bolt holes, and the inner ring of the connecting hole of the second flange is provided with connecting threads, which can be used to connect with the output end of the angle grinder.

[0007] Preferably, the force-relieving device is configured as a circular ring body, the outer side of the force-relieving device is wavy, and the inner wall of the force-relieving device is provided with the connecting thread, which can be used to connect with the output end of the angle grinder.

[0008] Preferably, the material of the force-dissipating device has a fracture torque that can be triggered greater than the normal operating torque of the angle grinder, and the material of the force-dissipating device has a fracture torque that can be triggered less than the ultimate recoil torque of the angle grinder.

[0009] Preferably, the energy dissipation device is provided with connecting rings at opposite ends, and the connecting holes can be used to connect and fix bolts to the bolt holes.

[0010] Preferably, the elastic buffer layer is made of high-performance rubber composite material.

[0011] Preferably, the elastic buffer layer is integrally connected to the resin grinding wheel and the first flange by hot pressing.

[0012] Preferably, the thickness of the elastic buffer layer is 1.5mm-3mm.

[0013] Preferably, the crack suppression mesh is configured as a radially oriented fiber mesh, wherein the fiber arrangement direction of the radially oriented fiber mesh extends from the side near the first flange toward the outer edge of the resin grinding wheel, and the fiber density of the radially oriented fiber mesh decreases from the side near the flange toward the outer edge of the resin grinding wheel.

[0014] The application employs the above technical solution and has at least the following beneficial effects: By installing a stress-relieving device between the first and second flanges, this device can quickly collapse or break after the angle grinder output end seizes, effectively absorbing and dispersing the impact torque and preventing the recoil force from being transmitted to the operator, thus significantly improving operational safety. An elastic buffer layer is provided between the resin grinding wheel and the first flange. This layer is made of high-performance rubber composite material and is integrally formed with the grinding wheel and flange through hot pressing. It can effectively alleviate vibration and impact during grinding, improving operating comfort and grinding accuracy. A radially oriented fiber mesh is embedded inside the resin grinding wheel as a crack suppression mesh. The scientifically designed fiber arrangement direction and density gradient can effectively suppress the generation and propagation of cracks under high-speed rotation, extending the service life of the grinding disc. The parallel design of the double flanges, combined with the corrugated structure of the stress-relieving device and the fixing of the connecting ring bolts, ensures stable transmission under normal operating torque and timely failure protection in case of overload. The overall structure is reasonable and easy to install.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] A specific embodiment of this utility model provides an anti-lock angle grinder disc, mainly used to prevent the transmission of impact force caused by the output end locking during high-speed rotation of an angle grinder, thereby improving operational safety and the service life of the grinding disc. Figures 1 to 3 As shown, the anti-locking dead angle grinding disc mainly includes a central flange, a resin grinding wheel 1, a force dissipation device 4, an elastic buffer layer 5, and a crack suppression mesh.

[0020] Specifically, the central flange is provided in two sets, including a first flange 2 and a second flange 3, which are arranged in parallel, with the diameter of the first flange 2 being larger than the diameter of the second flange 3. The first flange 2 and the second flange 3 are connected by a stress-relieving device 4, which can collapse and dissipate force after the angle grinder output end locks, effectively absorbing and dispersing impact torque. The resin grinding wheel 1 is fixedly mounted on the outer ring of the first flange 2, and an elastic buffer layer 5 is provided between the resin grinding wheel 1 and the first flange 2 to buffer vibration and impact during the grinding process. A crack suppression mesh is embedded inside the resin grinding wheel 1 to suppress the propagation of cracks generated when the resin grinding wheel 1 rotates at high speed.

[0021] Furthermore, the outer ring of the connection holes of the first flange 2 and the second flange 3 is provided with several bolt holes, and the inner ring of the connection hole of the second flange 3 is provided with connecting threads 201 for connection to the output end of the angle grinder. The stress dissipation device 4 is a circular ring body with a wavy outer structure and connecting threads 201 on the inner wall, also for connection to the output end of the angle grinder. The material of the stress dissipation device 4 is specially selected so that its fracture torque is greater than the normal operating torque of the angle grinder, but less than the ultimate recoil torque of the angle grinder, ensuring stability during normal operation and timely fracture and stress dissipation in case of seizure.

[0022] The energy dissipation device 4 is provided with connecting rings 401 at opposite ends. The connecting rings 401 have holes and can be connected and fixed to the bolt holes on the first flange 2 and the second flange 3 by bolts 402, so as to realize the reliable connection between the energy dissipation device 4 and the flange.

[0023] The elastic buffer layer 5 is made of high-performance rubber composite material and is integrally connected to the resin grinding wheel 1 and the first flange 2 by hot pressing. The thickness of the elastic buffer layer 5 is preferably 1.5mm to 3mm, which ensures the buffering effect without affecting the overall rigidity and grinding performance of the grinding disc.

[0024] The crack suppression mesh is configured as a radially oriented fiber mesh, with the fiber arrangement extending from the side near the first flange 2 towards the outer edge of the resin grinding wheel 1, and the fiber density decreasing from the side near the first flange 2 towards the outer edge of the resin grinding wheel 1. This structure can effectively suppress cracks caused by centrifugal force and thermal stress during high-speed rotation of the resin grinding wheel 1, thus extending the service life of the grinding disc.

[0025] The working principle of this embodiment: After the angle grinder is started, the output end is connected to the second flange 3 and the force dissipation device 4 via the connecting thread 201, driving the entire grinding disc to rotate. When the grinding disc suddenly seizes due to external resistance or a problem with the angle grinder, the torque at the output end of the angle grinder increases sharply. When the force dissipation device 4 exceeds its design torque, it collapses or breaks, absorbing the impact energy and preventing the torque from being transmitted to the operator's hand, thus improving safety. At the same time, the elastic buffer layer 5 can reduce vibration and noise during the grinding process, while the crack suppression mesh effectively prevents the resin grinding wheel 1 from breaking and splashing.

[0026] The anti-lock grinding disc in this embodiment has a compact structure, is safe and reliable, and is suitable for grinding operations of various angle grinders under high load conditions.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
